WARNING: This product can expose you to chemicals that are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, visit www.P65warnings.ca.gov.Upgrading to a single mass flywheel conversion is a critical step when building a high performance BMW manual transmission setup. The factory dual mass flywheel is heavy and prone to failure under elevated power levels. The ACT 601030 XACT Streetlite Flywheel addresses this by replacing the complex multi piece unit with a lightweight, one piece chromoly steel design. Weighing just 17.9 lbs, it delivers a noticeable reduction in rotational inertia, significantly sharpening throttle response and acceleration while maintaining the durability needed for street or drag racing.
